摘要： A manufacturing method is provided. A preform is arranged over a surface of an inner mold line. The preform is folded over sides of the inner mold line. An end of the preform is clamped to a floating plate using a bladder-activated clamp. The floating plate is translated in a first direction to tension the preform into a shaped body. A plurality of compressing bladders are activated to apply compressive forces to the preform.

摘要： A forming device includes a blow-forming die and a shielding member. The blow-forming die includes a first die that protrudes from a first die holder towards a second die holder and a second die that protrudes from the second die holder towards the first die holder. The shielding member is configured to extend from the first die holder to the second die holder before the blow-forming die commences forming a flange part of a pipe in a sub-cavity part. The sub-cavity part is between a main cavity part and the shielding member. The shielding member is separated from the first die and the second die.

摘要： Exemplary vehicle structures include a frame component that provides greater strength and/or other desired properties to a vehicle structure. The frame component includes a first wall (6) and a second wall (7). The first and second walls each comprise at least one metal sheet. The first and second walls bound a sealed interior gap (28). Pressurized fluid is introduced into the sealed interior gap through at least one of the walls via a fluid connector (8). In some arrangements the gap includes a hermetically sealed pocket (110) that is bounded by a pocket wall (36). The pressurized fluid is delivered into the pocket interior area that is bounded by the pocket wall. The fluid delivered to the sealed interior gap and/or the pocket interior area may be operative to cause controlled permanent deformation thereof to produce desired wall configurations which have increased strength. The fluid housed within the sealed interior gap may provide increased strength or other desired properties. Vehicle structures such as vehicle side frames, vehicle floor members and vehicle frame longitudinal members may each include one or more of the frame components integrated in the vehicle structure.

摘要： A forming assembly for forming a wick is disclosed. The forming assembly includes a tube inflatable to an inflated configuration. A wick mesh is configured to be wrapped about the tube. The forming assembly further includes a sheath positionable about the tube and the wick mesh. The tube and the sheath are configured to compress the wick mesh and form the wick based on the tube inflating towards the inflated configuration.

摘要： The present invention discloses a method for pressure forming of an aluminum alloy special-shaped tubular component by using an ultra-low temperature medium. By means of the characteristics that the forming property of an aluminum alloy tube is greatly improved under ultra-low temperature conditions, a tube is cooled and pressurized in a die through an ultra-low temperature medium, so that the tube forms a special-shaped tubular component at an ultra-low temperature. In the method for pressure forming of an aluminum alloy special-shaped tubular component by using an ultra-low temperature medium, the ultra-low temperature medium is not only used for cooling the die and the tube, but also used for pressurization to achieve flexible loading of the tube, which is favorable for forming complex special-shaped tubular components with varied cross-sections.

摘要： The invention relates to a roof rack roof rack for a motor vehicle, having a roof rail profile. The roof rail profile is manufactured from a profile that has a constant cross-section in the longitudinal direction of the profile. Roof rail profiles with different designs can be formed from one and the same profile cross-section, namely by the shaping of a side or wall section present on the profile that delimits a passage. The roof rail profile, which preferably is designed as one piece, has different cross-sections in the longitudinal direction, namely unshaped surface sections and shaped surface sections.
